(a) Employees benefiting under a plan—(1) In general. Except as provided in paragraph (a)(2) of this section, an employee is treated as benefiting under a plan for a plan year if and only if for that plan year, in the case of a defined contribution plan, the employer receives an allocation taken into account under § 1.401(a)(4)-2(c)(2)(ii), or in the case of a defined benefit plan, the employee has an increase in a benefit accrued or treated as an accrued benefit under section 411(d)(6).
(2) Exceptions to allocation or accrual requirement—(i) Section 401(k) and 401(m) plans. Notwithstanding paragraph (a)(1) of this section, an employee is treated as benefiting under a section 401(k) plan for a plan year if and only if the employee is an eligible employee under the plan as defined in § 1.401(k)-1(g)(4) for the plan year. Similarly, an employee is treated as benefiting under a section 401(m) plan for a plan year if and only if the employee is an eligible employee as defined in § 1.401(m)-1(f)(4) for the plan year.
(ii) Section 415 limits
(A) General rule for defined benefit plans. In determining whether an employee is treated as benefiting under a defined benefit plan for a plan year, plan provisions that implement the limits of section 415 are disregarded. Any plan provision that provides for increases in an employee's accrued benefit under the plan due solely to adjustments under section 415(d)(1), additional years of participation or service under section 415(b)(5), or changes in the defined contribution fraction under section 415(e) is also disregarded, but only if such provision applies uniformly to all employees in the plan.
(B) Defined benefit plans taking section 415 limits into account under section 401(a)(4) testing. Paragraph (a)(2)(ii)(A) of this section does not apply in the case of a defined benefit plan that uses the option in § 1.401(a)(4)-3(d)(2)(ii)(B) to take into account plan provisions implementing the provisions of section 415 in determining accrual rates under the section 401(a)(4) general test.
(C) Defined contribution plans. A defined contribution plan is permitted to apply the rule in the first sentence of paragraph (a)(2)(ii)(A) of this section in determining whether an employee is treated as benefiting under the plan, provided it applies the rule on a consistent basis for all employees in the plan.
(iii) Certain employees treated as benefiting
(A) In general. An employee is treated as benefiting under a plan for a plan year if the employee satisfies all of the applicable conditions for accruing a benefit or receiving an allocation for the plan year but fails to have an increase in accrued benefit or to receive an allocation solely because of one or more of the conditions set forth in paragraphs (a)(2)(iii) (B) through (F) of this section.
(B) Certain plan limits. The employee's benefit would otherwise exceed a limit that is applicable on a uniform basis to all employees in the plan. Thus, for example, if the formula under a defined benefit plan takes into account only the first 30 years of service for accrual purposes, an employee who has completed more than 30 years of service is still treated as benefiting under the plan.
(C) Benefits previously accrued. The benefit previously accrued by the employee is greater than the benefit that would be determined under the plan if the benefit previously accrued were disregarded. This could happen, for example, when the plan is applying the wear-away formula of § 1.401(a)(4)-13(c)(4)(ii) and the employee's frozen accrued benefit exceeds the benefit determined under the current formula.
(D) Benefit offset arrangements. The plan offsets the employee's current benefit accrual under an offset arrangement described in § 1.401(a)(4)-3(f)(9) (without regard to whether the offset is attributable to pre-participation service or past service).
(E) Target benefit plans. In the case of a target benefit plan that satisfies the nondiscriminatory amount requirement of § 1.401(a)(4)-1(b)(2) by satisfying the safe harbor in § 1.401(a)(4)-8(b)(3), the employee's theoretical reserve is greater than or equal to the actuarial present value of the fractional rule benefit.
(F) Post-normal retirement age adjustments. The employee has attained normal retirement age under a defined benefit plan and fails to accrue a benefit because of the provisions of section 411(b)(1)(H)(iii) regarding adjustments for delayed retirement.
(iv) Section 412(i) plans
(A) General rule. Notwithstanding paragraph (a)(1) of this section, an employee is treated as benefiting under an insurance contract plan within the meaning of section 412(i) for a plan year if and only if a premium is paid on behalf of the employee for the plan year.
(B) Exceptions. Notwithstanding paragraph (a)(2)(iv)(A) of this section, an employee is treated as benefiting under an insurance contract plan within the meaning of section 412(i) for a plan year if the sole reason that a premium is not paid on behalf of the employee is one of the reasons described in paragraph (a)(2)(iii) of this section. In addition, an employee is treated as benefiting under an insurance contract plan, within the meaning of section 412(i), that is a defined benefit plan if a premium is not paid on behalf of the employee solely because the insurance contracts that have previously been purchased on behalf of the employee guarantee to provide for the employee's projected normal retirement benefit without regard to future premium payments.
(3) Examples. The following examples illustrate the determination of whether an employee is benefiting under a plan for purposes of section 410(b).

Example 1.

An employer has 35 employees who are eligible under a defined benefit plan. The plan requires 1,000 hours of service to accrue a benefit. Only 30 employees satisfy the 1,000-hour requirement and accrue a benefit. The five employees who do not satisfy the 1,000-hour requirement during the plan year are taken into account in testing the plan under section 410(b) but are treated as not benefiting under the plan.

Example 2.

An employer maintains a section 401(k) plan. Only employees who are at least age 21 and who complete one year of service are eligible employees under the plan within the meaning of § 1.401(k)-1(g)(4). Under the rule of paragraph (a)(2)(i) of this section, only employees who have satisfied these age and service conditions are treated as benefiting under the plan.

Example 3.

The facts are the same as in Example 2, except that the employer also maintains a section 401(m) plan that provides matching contributions contingent on elective contributions under the section 401(k) plan. The matching contributions are contingent on employment on the last day of the plan year. Under § 1.401(m)-1(f)(4), because matching contributions are contingent on employment on the last day of the plan year, not all employees who are eligible employees under the section 401(k) plan are eligible employees under the section 401(m) plan. Thus, employees who have satisfied the age and service conditions but who do not receive a matching contribution because they are not employed on the last day of the plan year are treated as not benefiting under the section 401(m) portion of the plan.

(b) Former employees benefiting under a plan
(1) In general. A former employee is treated as benefiting for a plan year if and only if the plan provides an allocation or benefit increase described in paragraph (a)(1) of this section to the former employee for the plan year. Thus, for example, a former employee benefits under a defined benefit plan for a plan year if the plan is amended to provide an ad hoc cost-of-living adjustment in the former employee's benefits. In contrast, because an increase in benefits payable under a plan pursuant to an automatic cost-of-living provision adopted and effective before the beginning of the plan year is previously accrued, a former employee is not treated as benefiting in a subsequent plan year merely because the former employee receives an increase pursuant to such an automatic cost-of-living provision. Any accrual or allocation for an individual during the plan year that arises from the individual's status as an employee is treated as an accrual or allocation of an employee. Similarly, any accrual or allocation for an individual during the plan year that arises from the individual's status as a former employee is treated as an accrual or allocation of a former employee. It is possible for an individual to accrue a benefit both as an employee and as a former employee in a given plan year. During the plan year in which an individual ceases performing services for the employer, the individual is treated as an employee in applying section 410(b) with respect to employees and is treated as a former employee in applying section 410(b) with respect to former employees.
(2) Examples. The following examples illustrate the determination of whether a former employee benefits under a plan for purposes of section 410(b).

Example 1.

Employer A amends its defined benefit plan in the 1995 plan year to provide an ad hoc cost-of-living increase of 5 percent for all retirees. Former employees who receive this increase are treated as benefiting under the plan for the 1995 plan year.

Example 2.

Employer B maintains a defined benefit plan with a calendar plan year. In the 1995 plan year, Employer B amends the plan to provide that an employee who has reached early retirement age under the plan and who retires before July 31 of the 1995 plan year will receive an unreduced benefit, even though the employee has not yet reached normal retirement age. This early retirement window benefit is provided to employees based on their status as employees. Thus, although individuals who take advantage of the benefit become former employees, the window benefit is treated as provided to employees and is not treated as a benefit for former employees.

Example 3.

The facts are the same as Example 2, except that on September 1, 1995, Employer B also amends the defined benefit plan to provide an ad hoc cost-of-living increase effective for all former employees. An individual who ceases performing services for the employer before July 31, 1995, under the early retirement window, and then receives the ad hoc cost-of-living increase, is treated as benefiting for the 1995 plan year both as an employee with respect to the early retirement window, and as a former employee with respect to the ad hoc COLA.
